Patent DE-4123637-A1 (DE)
Title: Vehicle antilock brake system with vacuum servo - uses valves for controlled venting of servo regulating braking pressure
Inventor: KOLLERS MICHAEL
IPC: B60T8/44
Filed: 1991-07-17
Abstract: The vacuum servo has a vacuum section (54, 56) linked to the inlet manifold, and a working section (55, 57) alternately linked to the inlet manifold or to the atmosphere. The diaphragm separating the two sets of sections is spring loaded into a rest position. To speed up the return movement of the diaphragm, the two sets of chambers are linked during brake release, leaving the diaphragm to move rapidly. When the working section section is linked to the inlet manifold, for subsequent setting of the servo, the connection between the sections is blocked. The control valves for the servo sections are controlled via an anti-lock control circuit, using anti-lock control logic. ADVANTAGE - Improved brake response, simple brake control.

Title: Automatic repair of broken spark machine wire electrode - involves displacement of advanced into groove in workpiece between exit and entry wire guides
Inventor: IWASAKI TAKESHI
IPC: B23H7/10
Filed: 1991-09-27
Abstract: After removal of the broken part, the wire electrode (3) is advanced in the direction of the workpiece (1) unitl contact is detected (40a).  The wire is then moved horizontally within a predetermined range until the end falls within the machining groove (14) and contact is broken. The advance is resumed until the wire is stretched between two guides (4,5).  Within the groove (14) its attitude is constrained by a water jet (7) and suction pump (3). ADVANTAGE - Rapid and reliable repair is possible even where the machining groove has a narrowed gap, past which the electrode cannot move.
Patent DE-4134480-A1 (DE)
Title: Decontamination of fly ash and filter dust from combustion plant - involves heating to high temp. with air in rotary calciner and recycling flue gas to combustion, useful for removal of dioxin(s) and furan(s) and prevents environmental pollution
Inventor: WASSER HEINZ DIPL ING
IPC: A62D3/38
Filed: 1991-10-18
Abstract: In decontamination of fly ash and filter dust from combustion plant by heating above 800 deg.C, the hot dust accumulating in the flue gas chamber and final sepn. is passed directly in closed pipes into a rotary calciner, together with air for combustion and heated to min. 800 deg.C under slightly reduced pressure and the resultant flue gas is recycled to the hot zone of the combustion plant. Pref. the dusts are collected in a collector and then passed continuously into the rotary calciner, where they are heated to 900-1050 deg.C at 0.2-0.6 mbar. The rotary calciner is close to the combustion plant. The calciner and opt. dust collector are in a closed chamber, kept under slightly reduced pressure and the waste air from this is added to the air for combustion supplied to the combustion plant. USE/ADVANTAGE - The process is simple and economical and is useful for decontamination (e.g. removal of dioxins and furans), even of small amts. of dust, to prevent environmental pollution. Treatment whilst the dust is still hot reduces the energy requirement and prevents it agglomerating by cooling, which would make decontamination more difficult.

Filed: 1991-12-12
Abstract: A combined ring and clasp safety device (20, 21) for a hand-grenade has, for securing a resiliently biassed hand- grenade lever (4) (Fig 1 not shown), a ring (21) which can be clipped-in between resilient limbs 7 and 8 on a protective cap (3) as well as a clasp (22) (Fig 3 not shown) connected hingedly at 23 to the ring (21). The clasp has plug-in pin (24) which secures the protective cap (3) and the hand-grenade lever (4) together in a form-locking or interengaging connection with the hand-grenade. A locking pin (25) of the clasp possesses a hook (26) which prevents an extraction of the plug-in pin (24) upon a pure tractive stress at the ring (21) or at the plug-in pin (24). For the arming, a coupled rotary/tractive motion by way of the ring (21) is necessary, in which respect a minimum rotation corresponding to the length of the hook (26) past the roots of the limbs (7) is necessary. <IMAGE>

Patent DE-4143056-A1 (DE)
Inventor: TAPAVICZA STEPHAN VON DR
IPC: C10L1/22
Filed: 1991-12-30
Abstract: The invention concerns the use of (A) esters of phosphoric acid and/or their partial salts with alkoxylated aliphatic, cycloaliphatic and/or aromatic alcohols and/or (B) fatty-acid oligo-dialkanolamides as inhibitors to prevent the formation of organic-based incrustations from fluid hydrocarbon mixtures which show a tendency to produce such incrustations. Preferred inhibitors have surfactant properties and are capable of wetting the surfaces of solid materials and, in particular, spreading out over such surfaces, even in the presence of fluid hydrocarbons. They are particularly suitable for use as additives to crude oils and/or oil fractions which show a tendency to form incrustations.

Title: Optoelectronic distance sensor for motor vehicles, in particular passenger cars and utility vehicles with vision-impairing bodies
Inventor: SCHLIEBS GUENTER DIPL ING
IPC: G01S17/931
Filed: 1993-03-02
Abstract: An infrared reflex light sensor which acts in a contactless fashion has fading out of the background, and is used in industrial systems in a large number of areas of production and transport for monitoring, counting and control purposes is proposed as a distance sensor for motor vehicles, in particular for monitoring collisions between vehicles. An LED whose light is reflected into the interior rear-view mirror of the vehicle is used for display purposes. In this simplest form of the evaluation, the information via the safety distance passes directly into the driving process. An extension of the sensor electronics may be necessary, not for technical reasons but in order to achieve adaptation to the safety regulations applying to motor vehicles, such that when the voltage of the vehicle's electrical system is applied a short virtual reception signal occurs as a sign of the operational capability of the sensor. <IMAGE>
